/* PR c/4389
This testcase failed because host_integerp (x, 0) was returning
1 even for constants bigger than 2^31. It fails under under hpux
without -mdisable-indexing because the pointer x - 1 is used as
the base address of an indexed load. Because the struct A is not
actually allocated, x - 1 lies in the text segment and this causes
the wrong space register to be selected for the load. */
/* { dg-do run } */
/* { dg-options "-O2" } */
/* { dg-options "-O2 -mdisable-indexing" { target hppa*-*-hpux* } } */
/* Disable the test entirely for 16-bit targets. */
